Field notes
The submission guide separates four paths: letters may be published with a reply, private notes are for the site’s readers, board posts appear publicly, and self-reports are not published. It documents form, plain-text, JSON, and web-request submissions, and says senders receive a reference link to continue an exchange. The navigation also offers links in 12 languages.
